高度百分比不起作用

Question

正如你在这个jsfiddle http://jsfiddle.net/Grek/yLrC8/上看到的那样，我试图为我的文章DIV设置70％的高度，以使DIV的高度始终等于用户浏览器大小的70％（但是最小高度为400px）但对某些rason来说它不起作用。你知道为什么吗？感谢

Answer 1

您可以尝试这样的事情：

.article {
    position:absolute;
    text-align:justify;
    width: 450px;
    min-height:400px;
    height:70%;
    right:0;
    padding: 50px 32px 49px 62px;
    margin-right:75px;
    z-index: 15;
    margin-top: 90px;
    background: #ccc;
    overflow-y: scroll !important;
}

定位article绝对，你也可以准确地定义你想要它的位置（例如，形成顶部的距离和距离范围底部的距离），而不是我现在设置的浮动{{1} }。现在你只需要将正确的（你想要的那个）父母容器设置为具有一定高度的right:0;，所以你使用你想要的70％。

如果您希望窗口/视口与其范围相同，则必须将其定位position:relative;。
